On the Syntheses and Characteristics of the Sensitive Reagent of Dicyclopentadienyl-1, 1'-Diparanitroaniline Diamide Phosphate

应用二茂铁为原料 ,经由甲酰基化、氧化和酰氯化反应得到二茂铁二酰氯 ,继而与对硝基苯胺作用合成的二茂铁 - 1,1'-二对硝基苯胺二酰胺 ;通过红外、紫外可见光谱及差热扫描、元素分析对其进行表征 ,确证新化合物的元素组成 ,并对其进行结构鉴定。该实验还考察了二茂铁 - 1,1'-二对硝基苯胺二酰胺对磷酸盐的响应情况 ,表明二茂铁 - 1,1'-二对硝基苯胺二酰胺在酸性下对 H2 PO4-的响应不大 ,在微碱性条件下 ,体系在 λ=4 40 nm处颜色加深 。

By the reaction of formylatation, oxidation and acyl-chloridization, the dicyclopentadienyl diacid chloride is derived from dicyclopentadienyl iron, then is combined into dicyclopentadienyl-1, 1'-diparanitroaniline diamide, which has been found on no documents, with the reaction of paranitroaniline. By means of the infrared and ultraviolet visible spectrum and differential thermal scanning and elementary analysis, the composition has been attributed to them. To make a conclusive evidence of the elementary composition and a structural identification for this new chemical compound. The reaction of the dicyclopentadienyl-1, 1'-diparanitroaniline diamide with phosphate shows that the dicyclopentadienyl-1, 1'-diparanitroaniline diamide is in lesser response to H2PO4- under the acid environment, but is sensitive to phosphate under the alkalescent environment when their colours deepen in λ=440 nm.
